Refrigerant Line Sets Can Cause Compressor Failures
Jan 04, 2003· So, the linear length of the suction line plus the equivalent length of the fittings in that line is the equivalent length of the suction line. Sizing The Liquid Line Liquid lines have similar design limitations as suction lines. A liquid line that is too small will have too much pressure drop. This can cause the liquid to begin to boil before

Tips for Using Pulsation Dampeners in Dosing or Volumetric
Apr 03, 2015· The pulsation dampener at the suction of the pump has the same task as the one at the discharge—to keep the velocity and pressure of the liquid as constant as possible. If the low pressure at the suction stays relatively constant, the liquid is less likely to reach the vapor tension. This greatly reduces the main risk for cavitation.

Suction Nozzle - an overview | ScienceDirect Topics
Suction and discharge nozzles are on either the underside or the top of the compressor. In multistage compressors, two or more inlet nozzles may be provided; the suction lines are connected to suction drums controlled to maintain the various inlet pressures.
What is the discharge of a pump? - Quora
The suction pressure of a pump is a function of density and density of vapor or gases are far lower than that of liquids so either the pump won''t pump or there may be pumping if the cavitation is occurring in the impeller blades and not the eye of the impeller and the vapor generated will collapse at the region of high pressure at the discharge causing damage to impeller and …

How to Read a Pump Curve: Complete Guide
Nov 17, 2020· As discharge pressure increases, keeping viscosity constant, more fluid slips from the discharge side to the suction side of the pump, so the pump must spin at a higher RPM to maintain output. In Fig. 8, a positive displacement pump curve shows the influence of viscosity on slip with a correction chart.
How does a gear pump work?
The suction channel is loed at the point where the gear teeth come out of mesh, and the discharge channel is loed at the point where they go into mesh. A crescent-shaped seal ensures the suction area is separated from the discharge area. Without this , fluid will simply keep on flowing inside the pump.

Selecting The Right Relief Valve For Gear Pumps
The external relief valve serves a similar purpose as the internal relief valve, diverting fluid flow to alleviate excessive pressure in the discharge line. However, instead of being continuously circulated through the pump, fluid is diverted back into the feed tank or into the suction line upstream of the pump.
Graham Corporation Technical Article: Cavitation in Liquid
In this instance, the suction load to the pump can be manipulated via an air bleed, if the process allows, or a recycle line which would bring process from the discharge back to the pump’s suction. By manipulating the load you can control the pump’s suction pressure, raising the suction pressure to prevent cavitation.
